HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 636, 501, 567, 247 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 636, 501, 567, 247 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 636, 501, 567, 247 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 636, 501, 567, 247 is 1.
HCF(636, 501, 567, 247) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 636, 501, 567, 247 is 1.
Step 1: Since 636 > 501, we apply the division lemma to 636 and 501, to get
636 = 501 x 1 + 135
Step 2: Since the reminder 501 ≠ 0, we apply division lemma to 135 and 501, to get
501 = 135 x 3 + 96
Step 3: We consider the new divisor 135 and the new remainder 96, and apply the division lemma to get
135 = 96 x 1 + 39
We consider the new divisor 96 and the new remainder 39,and apply the division lemma to get
96 = 39 x 2 + 18
We consider the new divisor 39 and the new remainder 18,and apply the division lemma to get
39 = 18 x 2 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 636 and 501 is 3
Notice that 3 = HCF(18,3) = HCF(39,18) = HCF(96,39) = HCF(135,96) = HCF(501,135) = HCF(636,501) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 567 > 3, we apply the division lemma to 567 and 3, to get
567 = 3 x 189 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 567 is 3
Notice that 3 = HCF(567,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 247 > 3, we apply the division lemma to 247 and 3, to get
247 = 3 x 82 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 247 is 1
Notice that 1 = HCF(3,1) = HCF(247,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
